Question

please solve this sum in photograph ​

Answer 1

Answer:

Step-by-step explanation:

1/2(2x+3y) +12/7(3x-2y) = 1/2

take LCM

7(3x-2y) +24(2x+3y)/14(3x+2y)(3x-2y) = 1/2

21x -14y +48x+72y/14((3x)² - (2y)² = 1/2

69x + 68y/14(9x² - 4y²) = 1/2

69x + 68y = 63x² - 28y²

can you simplify it further, I am like tired.... sorry

Answer 2

Step-by-step explanation:

1/2(2x+3y) +12/7(3x-2y) = 1/2

take LCM

7(3x-2y) +24(2x+3y)/14(3x+2y)(3x-2y) = 1/2

21x -14y +48x+72y/14((3x)² - (2y)² = 1/2

69x + 68y/14(9x² - 4y²) = 1/2

69x + 68y = 63x² - 28y²

the next step our teacher didnt teach us!!
